Blew out the ankle twice this year. Based on discussions on BOS, have decided on the OB4 but have a few questions for those in the know:
1) Anyone tried the Roxa shells now offered with the system? If so, thoughts?
2) I have Stradas currently. How well do these work with OB4?
3) In the off chance someone has tried both Stradas and Roxa, comparisons?
